I could feel the heat coming off it when I stood next to the repaved section. They didn't repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.
A quick lesson on logical reasoning:
If you want to show that a piece of technology A is inefficient and you know that another piece of tech B is more efficient, then you can use the inefficiency of B as evidence for the inefficiencies of A. Basically, for some inefficiency threshold T where any value above T is poor efficiency, then A>B and B>T means that A>T.
Here, we're comparing vapour-compression (A) and solid state (B) heat pumps. Solid states are much more inefficient. So you have AT. You can't use this to make any claims about the relationship between A and T.
